Application filed May 20,

The present invention relates to an electric terminal construction, and has for its object to provide a device of this character which is inexpensive in its construction and can be used in connection with any form. of electrical tool or appliance where a plug and socket con nection is desired.

Further objects of the invention are to provide a device of this character which can be manufactured very economically, which can be readily applied to any form of electrically heated or operated device, and which provides a quick and effective means for making or breaking the electrical connection. 7

While one particular embodiment of the invention is shown and described in this application for illustrative purposes it will; be understood thatmany modifications and changes can be made without departing from the spirit of the invention. l

For a. full understanding of theinvention reference is to be had to the following description and accompanying drawings, in which Figure 1 is a front elevation of a plate having one of the terminal sockets mounted thereon.

Figure 2 is a horizontal sectional view on the line 22 of Figure 1, looking in the direction of the arrows.

Figure 3 is a horizontal sectional view through the device on the line 3-3 of Figure 1.

Figure 4 is a rear view of the device.

Corresponding and like parts are referred to in the following description and indicated on all of the views of the drawing by like reference characters.

Referring to the drawings, the reference character A designates an elongated socket into which a set of terminal'pins 1 project. The terminal pinsare carried by a block 2 of lava or other insulating material which is secured to the socket at the back thereof. The

' rear ends of the terminal pins extend through openings in the lava block 2 and are threaded 1926. Serial No. 110 497 Each of the socket sections 3 includes a subv stantially 'flat middle vportionb and vend wings. 15" which are curved laterally, one of the end Wings-being formed with an offset flange 5 \Vhen thetwo socket sections are assembled from. opposite sides .the laterally curved end wings thereof abut against each other, the off-set flanges 5 being arranged the other socket section to provide a close oint. The fiat middle portion of each of the socket sections islformed with a rearwardly extending tang 5 The lava block 2 is re ceived between the two tangs 5 of the respective socket sections and fits: againstthe laterally curved ends. 5? of the socket sections, being held in position by means of fastening members or screws 6 which extend through fitting against the plate 7 and being secured thereto by suitable fastening members 9, while the other arm of thebracket fits against the top of the socket and is engaged by the screws 6. These screws 6 thus perform the triple fun ction of holding the lava; block inposition. securing the, two socket sections together and fastening the socket to the supporting bracket. As shown on the drawings the lava block is provided with three terminal pins "1 which v project into the socket from the back there: of, although it willbe understood that a lesser or a greater number of the terminal pins may be used as is necessary. Any conat B may be employechsaid plug bein adapted to slip over certain of the terminal pins and establish an electrical connection therewith. i

at opposite ends of the socket and each of the off-setflanges fitting around the end of vent-ional form of plug such as that indicated As previouslystated, the socket sections 5 r are similar and interchangeable, thereby avoiding the necessity of providing rights andlefts. A further important feature of the socket sections is that they are shaped so that each section can be bent into form at the same time that it is stamped out, thereby avoiding the expense of a second'operation.

The stamping and shaping of the socket sections is accomplished by one operation, and

engaging t sulaitin for this ltlzhfsoll the socket can beinianu'facturetl nlore economically than another socket which is designed so that after the stamping of the blanka second operation is required to I bend and shape the same, This is an important consideration and enables the sockets to'be very economically produced,

Having thus described my invention what I claim as new and desire to secure by Letters Patent is, y

1. A terminal "socket ineluding complemental socket sections adapted tobe iittcd against each other froniopposite directions,

an insulating block,fastening' member's" connectingthe socket sections together and also heinsulating block; and tenninal pins earned by the insulating block;

2. A terminal socket including co'Inpla mental socket sections adapted to be fitted a ainst each other froln'opp'osite directions, said socket sections being formed with tang 'p rtions, an insulating block rcceivedbetween the tang portions, fastening r'neinbers extehdin through the tan portions and in"- I block and servin 'hoth to secure the inslilat black in posit-ion and fasten the socket section's together, and terminal pins carried bythe insulating block.-

3.
